The Calculation of the Indispensable Accuracy of the Measuring of an EM-wave Energy

Abstract

The hypothesis of a «tired light» is now disclaimed by indirect signs. Within the framework of this hypothesis it is demonstrated, that the energy ?=hH (where h — Planck constant, H — Hubble constant ) is a value of energy that is lost by a photon in respect to one cycle of a light wave, irrespective of a wavelength. Only having exceeding of the indicated measurement accuracy of energy, it is possible to demonstrate absence or presence of «tired» light directly in experiment. But in case of the stationary Universe it is possible to test this hypothesis by the obtained exponential dependence between redshift and distance up to a source.
